Objective To study the clinical effects of pulmonary recruitment maneuvers combined with pressure regulation volume control (PRVC) in the treatment of severe respiratory distress syndrome (RDS) in premature infants.Method From July 2015 to September 2016,preterm infants of grade Ⅲ-Ⅳ RDS who received PRVC treatment in neonatal department of Huai'an Maternal and Child Health Hospital were assigned into recruitment maneuver group and control group (without recruitment maneuver) using randon number table.The ventilator parameters were observed at 1,2,6,12,18 h and 24 h after ventilation.Recovery rate,duration of oxygen therapy and ventilation,duration of hospital stay,incidence of second dose of pulmonary surfactant and complications were compared between two groups.Result A total of 18 cases were included in recruitment maneuver group and 19 cases in control group.The recovery rate of recruitment maneuver group was higher than control group (16/18 vs.10/19).The duration of oxygen therapy [(6.6 ± 2.3) d vs.(11.8 ± 3.0) d],duration of ventilation [(4.1 ± 2.3) d vs.(6.4 ± 2.8) d],duration of hospital stay [(26.7 ± 7.0) d vs.(33.0 ± 8.4) d] in recruitment maneuver group were significantly shorter than control group (P ＜ 0.05).The proportion of bronchopulmonary dysplasia (1/18 vs.8/19),retinopathy of premature (1/18 vs.7/19),patent ductus arteriosus that require medication closure (1/18 vs.7/19)and incidence of second dose of pulmonary surfactant (2/18 vs.9/19) in recruitment maneuver group were significantly lower than control group (P ＜ 0.05).While the complication of air leak,necrotizing enteritis,Ⅲ-V grade intracranial hemorrhage showed no significant differences between the two groups (P ＞ 0.05).Conclusion Recruitment maneuvers combined with PRVC in treatment of severe RDS premature infants can improve recovery rate and oxygenation.It can also shorten the duration of oxygen therapy,ventilation and hospital stay.It can reduce the incidence of bronchopulmonary dysplasia and retinopathy of premature.It is worth spreading in clinical practice.reduce the incidence of bronchopuhmonary dysplasia and retinopathy.It is worthy of promotion.

BACKGROUNDSleep deprivation (SD) has been used in treatment of depression disorder, and could effectively improve the patients' depressive symptoms.The aim of the study was to explore the effects of SD on electroencephalographic (EEG) and executive function changes in patients with depression.

METHODSEighteen depression patients (DPs) and 21 healthy controls (HCs) were enrolled in the present study. The whole night polysomnography (PSG) was recorded by Neurofax-1518K (Nihon Kohden, Japan) system before and after 36 hours of SD. The level of subjects' depression state was assessed by Visual Analogue Scale (VAS), and the executive function was assessed by Wisconsin Card Sorting Test (WCST).

RESULTSSignificantly decreased sleep latency (SL; before SD: (31.8 ± 11.1) minutes, after SD: (8.8 ± 5.2) minutes, P < 0.01) and REM sleep latency (RL; before SD: (79.8 ± 13.5) minutes, after SD: (62.9 ± 10.2) minutes, P < 0.01) were found after SD PSG in depression patients. Decreased Stage 1 (S1; before SD: (11.7 ± 2.9)%, after SD: (7.3 ± 1.1)%, P < 0.01) and Stage 2 (S2, before SD: (53.8 ± 15.5)%, after SD: (42.3 ± 14.7)%, P < 0.05) of non-rapid eye movement (NREM) sleep, and increased Stage 3 (S3, before SD: (11.8 ± 5.5)%, after SD: (23.6 ± 5.8)%, P < 0.01) and Stage 4 (S4, before SD: (8.8 ± 3.3)%, after SD: (27.4 ± 4.8)%, P < 0.01) NREM sleep were also found. After SD, the depression level in patients decreased from 6.7 ± 2.1 to 2.9 ± 0.7 (P < 0.01). In WCST, the patients showed significantly decreased Response errors (Re, before SD: 22.3 ± 2.4, after SD: 18.3 ± 2.7, P < 0.01) and Response preservative errors (Rpe, before SD: 11.6 ± 3.6, after SD: 9.3 ± 2.9, P < 0.05). Depression patients' RE (t = 2.17, P < 0.05) and Rpe (t = 2.96, P < 0.01) also decreased significantly compared to healthy controls.

CONCLUSIONSD can improve depression symptom and executive function in depression patients.

Objective:To investigate the effects of different preoperative biliary drainage methods on bile bacterial culture and drug resistence of malignant obstructive jaundice.Methods:The retrospective and descriptive study was conducted. The clinical data of 317 patients with malignant obstructive jaundice who were admitted to the First Medical Center of Chinese PLA General Hospital from January 2015 to December 2018 were collected. There were 216 males and 101 females, aged (62±10)years. Of 317 patients, 158 cases had no preoperative biliary drainage, 115 received preoperative biliary drainage by percutaneous transhepatic choledochal drainage (PTCD), 44 received preoperative biliary drainage by endoscopic retrograde biliary drainage (ERBD). Observation indicators: (1) bile bacteria in different preoperative biliary drainage methods; (2) clinicopathological characteristics of patients with positive bile bacteria; (3) drug resistance of bile bacteria in different methods of preoperative biliary drainage. Measurement data with normal distribution were expressed as Mean± SD. Count data were expressed as absolute numbers or percen-tages, and comparison between groups was analyzed by the chi-square test. Bonferroni correction was used for pairwise comparison. The inspection level was 0.016 7 in the multiple comparison. Results:(1) Bile bacteria in different preoperative biliary drainage methods: of 317 patients, 116 cases were positive for bacterial culture, including 168 strains of 43 bacterial types. There were 46 strains from 36 patients without preoperative biliary drainage, 49 strains from 39 patients with preoperative PTCD and 73 strains from 41 patients with preoperative ERBD. ① The positive rate of bacteria for 317 patients was 36.59%(116/317). The positive rates of bacteria for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD were 22.78%(36/158), 33.91%(39/115) and 93.18%(41/44). There was a significant difference in the positive rate of bacteria among the three groups ( χ2=74.066, P<0.05). There was no significant difference between patients with preoperative PTCD and patients without preoperative biliary drainage ( χ2=4.137, P>0.016 7), but there were significant differences between patients with pre-operative ERBD and patients without preoperative biliary drainage or patients with preoperative PTCD ( χ2=72.305, 44.718, P<0.016 7). ② The overall multiple bacterial rate was 36.21%(42/116). The multiple bacterial rates for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD were 19.44%(7/36), 23.08%(9/39) and 63.41%(26/41). There was a significant difference in multiple bacterial rate among the three groups ( χ2=20.431, P<0.05). There was no significant difference between patients with PTCD and patients without preoperative biliary drainage ( χ2=0.147, P>0.016 7), but there were significant differences between patients with preoperative ERBD and patients without preoperative biliary drainage or patients with preoperative PTCD ( χ2=15.133, 13.215, P<0.016 7). ③ The overall prevalence rate of multi-drug resistant organism was 30.95%(52/168). The prevalence rates of multi-drug resistant organism for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD group were 15.22%(7/46), 26.53%(13/49) and 43.84%(32/73). There was a significant difference in the prevalence rate of multi-drug resistant organism among the three groups ( χ2=11.447, P<0.05). There was no significant difference between patients with PTCD and patients without preoperative biliary drainage ( χ2=1.827, P>0.016 7). There was a significant difference between patients with preoperative ERBD and patients without preoperative biliary drainage ( χ2=10.497, P<0.016 7), but there was no significant difference between patients with preoperative ERBD and patients with preoperative PTCD ( χ2=3.772, P>0.016 7). (2) Clinicopatho-logical characteristics of patients with positive bile bacteria: age, the history of abdominal surgery, degree of jaundice and location of biliary obstruction of patients were not related to the positive rate of bacterial culture ( χ2=4.865, 1.423, 4.922, 0.030, P>0.05). (3) Drug resistance of bile bacteria in different methods of preoperative biliary drainage: for patients without preoperative biliary drainage, the drug resistance rate of Gram-positive bacteria to nitrofurantoin, linezolid and tigecycline was 0, and the drug resistance rate of Gram-negative bacteria to piperacillin/tazobactam, gentamicin, tobramycin, amikacin and imipenem was 0. For patients with PTCD, the drug resistance rate of Gram-positive bacteria to linezolid and tigecycline was 0. For patients with ERBD, the drug resistance rate of Gram-positive bacteria to linezolid and tigecycline was 0. In terms of Gram-positive bacteria, linezolid, tigecycline, vancomycin and nitrofurantoin were the top four antibiotics with the lowest resistance rate. In terms of Gram-negative bacteria, imipenem, piperacillin/tazobactam, amikacin and tobramycinn were the top four antibiotics with the lowest resistance rate. Seven strains of fungi showed no resistance to antifungal drugs. Conclusions:Patients with preoperative ERBD are more vulnerable to infectious complications, and more likely to form drug resistant organism and multi-drug resistant organism. For Gram-positive bacteria infection, linezolid, tigecycline and vancomycin can be used for treatment. For Gram-negative bacteria infection, imipenem, piperacillin/trzobactam, amikacin and tobramycin can be used for treatment.

Background/Aims: Metabolic dysfunction-associated steatohepatitis (MASH) is an unmet clinical challenge due to the rapid increased occurrence but lacking approved drugs. Autophagy-related protein 16-like 1 (ATG16L1) plays an important role in the process of autophagy, which is indispensable for proper biogenesis of the autophagosome, but its role in modulating macrophage-related inflammation and metabolism during MASH has not been documented. Here, we aimed to elucidate the role of ATG16L1 in the progression of MASH. Methods: Expression analysis was performed with liver samples from human and mice. MASH models were induced in myeloid-specific Atg16l1-deficient and myeloid-specific Atg16l1-overexpressed mice by high-fat and high-cholesterol diet or methionine- and choline-deficient diet to explore the function and mechanism of macrophage ATG16L1 in MASH. Results: Macrophage-specific Atg16l1 knockout exacerbated MASH and inhibited energy expenditure, whereas macrophage-specific Atg16l1 transgenic overexpression attenuated MASH and promotes energy expenditure. Mechanistically, Atg16l1 knockout inhibited macrophage lipophagy, thereby suppressing macrophage β-oxidation and decreasing the production of 4-hydroxynonenal, which further inhibited stimulator of interferon genes(STING) carbonylation. STING palmitoylation was enhanced, STING trafficking from the endoplasmic reticulum to the Golgi was promoted, and downstream STING signaling was activated, promoting proinflammatory and profibrotic cytokines secretion, resulting in hepatic steatosis and hepatic stellate cells activation. Moreover, Atg16l1-deficiency enhanced macrophage phagosome ability but inhibited lysosome formation, engulfing mtDNA released by pyroptotic hepatocytes. Increased mtDNA promoted cGAS/STING signaling activation. Moreover, pharmacological promotion of ATG16L1 substantially blocked MASH progression. Conclusions ATG16L1 suppresses MASH progression by maintaining macrophage lipophagy, restraining liver inflammation, and may be a promising therapeutic target for MASH management.

OBJECTIVE: To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. MATERIALS AND METHODS: A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. RESULTS: Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18-24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. CONCLUSION: Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair.

Objective: To compare the clinical effects of ganciclovir combined with dexamethasone and ganciclovir alone in the treatment of acute idiopathic facial neuritis. Methods: From March 2014 to March 2016, 80 patients with acute idiopathic facial neuritis admitted in the department of neurology of Luzhong Hospital were randomly divided into treatment group and control group according to the admission sequence, with 40 cases in each group.The two groups were given basic treatment (mecobalamine intramuscular injection + clonazepam and continuous application for 15d), and the treatment group was excluded from the corticosteroid application.On this basis, ganciclovir combined with dexamethasone was applied in the treatment group, and ganciclovir was applied in the control group.Both two groups had a course of 15 days.All the patients were graded by Portmann simple scale before treatment and at 7 days and 15 days after treatment, and statistical significance of SPSS13.0 software was adopted. Results: Intra-group comparison: after treatment of 7d, the score of the treatment group was (10.11±3.62)points, which was significantly higher than (2.60±2.22)points before treatment(t=1.432, P<0.05). The score had no statistically significant difference between 7d after treatment[(10.11±3.62)points] and 15d after treatment[(11.82±3.02)points] in the treatment group (t=1.582, P>0.05). In the control group, the score had no statistically significant difference between 7d after treatment[(3.22±3.12)points] and before treatment[(2.70±2.30)points] (t=0.923, P>0.05). Comparison between the two groups: there was no statistically significant difference in pre-treatment score between the two groups (P>0.05). The score of the treatment group at 7d after treatment[(10.11±3.62)points] was significantly different from that of the control group[(3.22±3.12)points](t=1.633, P<0.05). There was no statistically significant difference in scores between the two groups at 15d after treatment (P>0.05). Conclusion Ganciclovir combined with dexamethasone and ganciclovir alone are effective in the treatment of acute idiopathic facial neuritis.Although the improvement effect of the combined treatment is earlier than that of single use, there is no significant difference in the total effective rate between the two treatments.

Objective:In order to optimize the mode of biliary drainage, we compared the different drainage methods of preoperative biliary drainage in the treatment of malignant obstructive jaundice of distal bile duct.Methods:From January 2015 to December 2018, 166 cases of distal biliary malignant obstructive jaundice treated by operation in the First Medical Center of PLA General Hospital were collected. According to the preoperative biliary drainage mode, 85 cases were divided into non drainage group, 56 cases in PTBD group and 25 cases in ERBD group; according to the operation mode, 116 cases were divided into radical pancreatoduodenectomy group and 50 cases were divided into palliative cholangiojejunostomy group, each group was divided into three groups according to the drainage mode. Chi square test and ANOVA were used to compare the results of bile bacterial culture and perioperative conditions of each group.Results:The positive rate of bile bacteria culture in non drainage group, PTBD group and ERBD group is 22.4% (19/85), 28.6% (16/56) and 100% (25/25). The positive rate in ERBD group is higher than that in PTBD group and non drainage group, the difference is statistically significant ( P<0.05). The proportion of multiple bacteria in ERBD group is higher than that in PTBD group and non drainage Group [64.0% (16/25) vs. 12.5% (2/16) vs. 5.3% (1/19)], the difference is statistically significant ( P<0.05). The proportion of common pathogens in ERBD group is higher than that in PTBD group and non drainage Group [97.8% (45/46) vs. 89.5% (17/19) vs. 66.7% (14/21)], the difference is statistically significant ( P<0.05). In pancreatoduodenectomy group, the operation time of ERBD group is significantly longer than that of PTBD group and non drainage group [(334.5±48.3) min vs. (289.4±39.5) min vs. (303.9±57.1) min], the difference is statistically significant ( P<0.05). The amount of bleeding in PTBD group is less than that in ERBD group and non drainage group [(268.8±128.4) ml vs. (388.2±181.6) ml vs. (366.1±220.4) ml], the difference is statistically significant ( P<0.05). There is no significant difference in the incidence of complications after pancreatoduodenectomy among three ways of drainage ( P>0.05). The incidence of clinically relevant postoperative pancreatic fistula is 6.8% (4/59), 10.0%(4/40) and 29.4%(5/17) in non drainage group, PTBD group and ERBD group. ERBD group is higher than non drainage group, the difference is statistically significant ( P<0.05). In palliative cholangiojejunostomy, there is no significant difference in operation time, amount of bleeding, postoperative hospital stay and complications among all groups ( P>0.05). Conclusion:Compared with ERBD, PTBD is a more suitable choice for patients who need preoperative biliary drainage before pancreatoduodenectomy.

Sepsis is a complex syndrome caused by multiple pathogens and involves multiple organ failure, particularly spleen dysfunction. In 2017, the worldwide incidence was 48.9 million sepsis cases and 11 million sepsis-related deaths were reported (Rudd et al., 2020). Inflammation, oxidative stress, and apoptosis are the most common pathologies seen in sepsis. Liensinine (LIE) is a bisbenzylisoquinoline-type alkaloid extracted from the seed embryo of Nelumbo nucifera. Lotus seed hearts have high content of LIE which mainly has antihypertensive and antiarrhythmic pharmacological effects. It can exert anti-carcinogenic activity by regulating cell, inflammation, and apoptosis signaling pathways (Manogaran et al., 2019). However, its protective effect from sepsis-induced spleen damage is unknown. In this research, we established a mouse sepsis model induced by lipopolysaccharide (LPS) and investigated the protective effects of LIE on sepsis spleen injury in terms of inflammatory response, oxidative stress, and apoptosis.
